X11 Performance Header Options

8 posts in this topic

I'm looking to try and extract a few more HP's and torques from my X11...

 

I'm running GPR cans at the minute, but I believe less restrictive headers will also help...

 

I can't seem to find any performance headers anywhere on the net....

 

Not totally averse to a bit of tinkering to make fit, but I'm quite fond of my knuckles!

 

Any guidance would be most appreciated.

 

Also, once I have the system sorted, would a power commander help to get the most out of it?

Are we talking standard BB headers, or performance; if performnce, any guidance on which would be appreciated.

Thanks

I've been in touch with Delkevic and they reckon their BB headers are 38mm OD, compared to the standard X11's 36mm OD and they reckon they will fit the X11 without any mods....price is not too bad either, at £199?

Cheers!

Cheers Wayne, do you know if Akro do headers specifically for the X11 or are they sold as an upgrade for the BB?

The Acro system I have is specific to the X11 , a BB system won't have the o2 sensor fitting , altho you could fit an 02 eliminator
